摘要: Four-port microwave-integrated-circuit (MIC) edge-guided wave circulators (BGC) have been designed, fabricated, and tested. A mathematical characterization of the strip conductor's shape as well a precise mechanical control bias inhomogeneity are provided. By means these two techniques reproducibility device is greatly improved with respect to that EGC obtained by traditional cut-and-try methods. X-band performance data presented related spatial distribution effective magnetic permeability mu/sub eff/ in ferrite substrate. Experimental evidence reported an efficient circulator action occurs when eff/< 0 at some point under central circular shield. The RF electric field circulator's surface investigated probing technique. It found lower part operation band, fields considerable amplitude extend air region between guiding edge substrate's edge.
